TUB.

Specification of Letters Patent.

Patented Feb. 20, 1906. V

To all whom t may concern:

Be it known that I, PATRICK CONNOLLY, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Tubs, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to the construction of the outlet and overflow arrangements of tubs, and relates more especially to that class of tubs generally known as Hcompartmenttubs," in which two or more tubs or compartments are made or set up side by side and generally used for laundry purposes, and the invention is especially applicable to tubs of this kind which have two compartments.

Heretofore it has been the usual practice in making tlie outlet and overow connections of such tubs to run branch pipes from tlie waste-pipe to the outlet and overow of each compartment. This requires quite a considerable amount of pipe-fitting, which increases the cost of setting up the tubs, and the cost has been further increased by the necessity of setting a trap in the waste-pipe just beyond the branch pipes or a separate trap in each of the branch pipes.

My invention aims to improve and simplify and lessen the cost of the outlet and overflow connections of tubs, and especially of compartment-tubs, by providing a fitting to be attached to the under side of the tub to form a chamber into which open the outlet and overflowfrom each compartment and from which the waste-pipe leads and by so arranging the pipes leading into and from this chamber as to avoid the necessity of a trap being placed in the waste-pipe, and a further object of the invention is to prevent all backflow of water to the tubs, which object I accomplish by providing the outlet from the tubs, or from each compartment in case of a compartinent-tub, with a checkvalve of suitable construction, all as `will be hereinafter more fully described, and specifically pointed out in the claims.

All further preliminary description will be omitted, and a detailed description of a construction embodying the features of the invention in preferred forms will be given in connection with the drawings forming a part of this specification, in which- Figure l is a longitudinal sectional view of a two-part compartment-tub provided with my improved outlet and overiiow connections.l Fig. 2 is an enlarged detail view of said connections. Fig. 8 is a section on line 3 of Fig. 2. Fig. 4 is a section on line 4 of Fig. 2. Fig. 5 is a view similar to Fig. 2, but without the waste-pipe being extended up within the chamber to form a trap. Fig. 6 is a section on line 6 of Fig. 5.'

Referring first to Figs. l to 4, A is a compartment-tub having the tubs or compartments c c, and which may be of any usual construction, but is shown as constructed of wood with a pottery or stone lining. Se-

cured to-the under side of the tub is a casing b of such a shape as to form a chamber B beneath the tub. The casing b may be of any suitable shape and of any suitable material,

but is preferably a metal casting of about the shape shown, and it may be secured to the tub inv any suitable manner, preferably detachably, as by screws c c. Leading from .the chamber B is a waste-pipe 10, which may be connected to the casingin any vsuitable manner, but preferably as shown, the wastepipe proper being connected by a couplingnut 2 to an outlet. ipe or nozzle 3, passing through the casing and having a flange 4 inside the casing and having its outer portions threaded to receive a nut 5, by which it is secured to the casing, and to receive the coupling-nut 2. Outlet-pipes or wastes 11, 12 from the compartments a c are positioned so as to communicate with the chamber B, and the overflow-pipe 13, which is preferably placed in the partition between the compartments and has communication at its upper end with bothcompartments, a single pipe thus serving to take the overflow from both compartments, also leads into the chamber B. lt will be seen that the casing b forms a fitting which may be easily attached to and readily detached from almost any form of tub/and that in setting up a tub with one of the casings attached it is necessary only to connect the waste-pipe to the outlet of the chamber in order to provide for carrying away the waste water and overfiow from both or. all of the compartments, and as the IOO casings may be very cheaply made and attached to the tubs much trouble and expense is saved by the use of such casings.

To prevent the waste water backing up through the outlets 11 and 12 into the tubs, I provide the outlets 11 and 12 with suitable check-valves 15 and 16, which may be of any suitable form and material, but preferably are made of suitable sheet metal, as sheet copper or brass, pressed to about the shape shown, and are preferably supported on rods 17, which rods are carried by cross-pieces within said outlets, the valves being free to slide vertically on said rods, and adjustably supported thereon by nuts 18.

By this construction all fiooding of the tubs due to backflow through the outlets from any cause whatever is prevented. If, for example, in the construction shown the compartment a is empty and water is flowing out of the compartment a', if the wastepipe 10 does not carry the water out of the chamber B as fast as it can fiow into the chamber B from the compartment a', so that water tends to flow from the chamber B into the compartment a, the valve 15 will rise and prevent any such backiiow of the water, so that if the stopper should have been left out of the outlet of the compartment a there will be nodanger of the water flowing back into that compartment when the other compartment is being emptied, or if the stopper is in place it will not be thrown out by back pressure. Providing check-valves in the outlets of the tubs to prevent backow into the tubs is in itself an important feature of the invention, and such valves may be used independently of the other features of the inventionas, for example, `check-valves may be arranged in out single tub. The application of check-valves in overflow-outlets of tubs is also to be understood as within the invention.

To avoid the necessity of a trap being glaced in the waste-pipe beyond the chamber I make the waste-pipe 10 communicate with the interior of the chamber B at a higher level than the outletipes 11 and 12 communicate therewith, sai outlet-pipes preferably extending some distance down into the chamber B and the waste-pipe or in the construction shown the outlet-pipe 3 extending up into said chamber above the level of the bottom of the outlet-pipes 1 1 and 12. The overflow-pipe 13 also extends down into the chamber B below the level of the top of the pipe 3. I thus provide a water seal or tra within the chamber B, which eifectually sea s the outlet-pipe 11 and 12 and the overflowpipe 13 against any gas which may flow back through the waste-pipe 10, and I thus avoid the additional expense of a trap to be inserted in the waste-pipe 10 beyond the chamber B and the labor of tting such a trap in place.

et-pipes which lead directly to a common waste-pipe or in the outlet from a ,applicablel to a tub having more than two compartments, the casing then being made 'of proper shape to embrace the outlets from all the compartments and the compartments being arranged so that their respective outlets may be quite near each other, as if there are four compartments by arranging them in pairs and back to back, as will be readily understood. The invention may be adapted to a tub having three compartments in a line by running a connecting-pipe from the chamber B to the outlet of the third tub.

Figs. 5 and 6 illustrate a construction in' which the waste-pipe is not extended up within the chamber to form a trap, in which case the ventipe 19 may be omitted, as shown. It will) also be understood that in such a construction it is not necessary to ,have the outlet-pipes 11 and 12 extend down into the chamber B.

Various modifications in the details of construction and arrangements of the parts described will suggest themselves to those skilled in the art, and it will be understood `that such modifications are within the invention.

What is claimed is- 1. The combination with a tub having two or more compartments, of a chamber beneath the tub formed by detachably securing a casing to the under side of the tub, outlets leading from said compartments to said chamber, and a waste-pipe leading from said chamber, substantially as described.

2. The combination with a tub having two or more compartments, of a chamber beneath the tub formed by detachably securing a casing b to the under side of the tub, outlets leading from said compartments to said chamber, check-valves on said outlets to prevent backflow, and a waste-pipe leading from said chamber, substantially as described.

3. The combination with a tub having two or more compartments, of a chamber beneath the tub formed byvdetachably securing a casing b to the under side ofthe tub, outlets leading from said compartments to said chamber, and a waste-pipe open to said chamber at a higher level than the openingsA of said outlets into the chamber, substantially as described.

4. The combination with a tub having two or more compartments, of a chamber beneath TOO IIO

' outlets into the chamber, substantially as described.
